Android Question What would cause "Total" value of FTP_UploadProgress to be "-1"?

[JohnC]

I am having a problem uploading to a windows server using a B4A app.

I am using 1.62 of the network, and the uploads just hang in the middle of the upload progress.

And when the progress sub event does fire, the "total" value provided is always "-1" even though the TotalUploaded is incrementing:

Sub FTP_UploadProgress (ServerPath As String, TotalUploaded As Long, Total As Long)

I am able to upload to the same ftp server from my windows PC no problem (using the same username/password/non-passive mode).

So, where does the "Total" value come from? Is it a variable stored in the B4A network library routine?

What could cause it to provide a "-1" value?

Total size will always show -1. The size is never known. The parameter should have not been there.

I'm confused....your own tutorial uses the "total" parameter in the "Upload" example:

https://www.b4x.com/android/forum/threads/android-ftp-tutorial.10407/

Also, since the file is uploading from the "device", why wouldn't the "size" be known/accessible to the Net Lib because the file is located on the device?

When I wrote the tutorial I wasn't aware to the fact that the way the FTP client is implemented causes it to never set the total size. It happens inside the wrapped library.
